GRAlN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 254,820, dated March14, 1882.

Application filed December 7, 1880.

1'0 all whom it may concern:

. Beitknown that I,ELLIs J. HOYLE, a citizen of the United States,residing atMartins Ferry, in the countyofBel montand State of Ohio, haveinvented certain new and useful Improvements 'inThrashingMachines andGrain-Separators;

andIdo herebydeclare the following to tea full, clear, and exactdescription of the inventioii, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawin gs, and to letters or figures ot'referencemarked thereon, which form a part of this specification.

This invention relates to thrashing-machines andgrain-scparators; anditconsists in the novel construction, combination, and arrangement ofparts, all as will be hereinafter fully described, and specificallypointed'out in the claim.

In the accompanying drawings, Figure 1. is a side view of athrashing-machine and separator with my improvements Fig. 2 is also aside View, partly in section. Fig. 3 is an end view, showing thevibrating levers. Fig. 4 is a detached view.

The general construction of the machine may be like other machines inuse, with the frame A supporting both the thrasher and separator.

In the drawings, 13 is the thrashing-cylinder, from which the straw andgrain are delivered upon the straw-carrier O in the usual manner.

The straw passes out at the rear of the machine, while the grain,falling on the bottom board, D, rolls down the inclined surface andfalls into the upper shoe, S, or upon the riddle E in the top of theshoe. In the rear part of this upper shoe is an inclined bottom, E,whichdirects the grain downward and backward to ward the fan to fall upon theshort riddle Fin the top of the lower shoe, S. The grain passes throughthis riddle and falls upon the screen G in the lower partof the lowershoe, to be discharged at spout a; but the tailings pass off at the rearend of the short screen F, and fall into the spout H, to be delivered tothe elevator I, and thus returned to the thrashing cylinder through thespout K.

The machineis set in motion by any suitable power applied by means ofshaft L, having a bevel-pinion, M, which gears int'o pinion N, thusgiving motion to wheel 0, which in turn gears into pinion P, to givemotion to the thrashing-cylinder B and the strawcarrier 0, abovementioned. By means of pulleys and (No model.)

band, Q, the elevator I is set in motion. The wheel 0 also gives motionto the fan-shaft R; but as no claim is made to the above, furtherdescription is not necessary.

The two shoes S and S are supported on the four levers T, which arepivoted at or near their middle, so as to freely vibrate or swing onpivots U. This vibrating motion is given to the levers by means of shaftV, crank --pin W, and pitman 0, connected with the lower shoe, S. Thusboth shoes are shaken by the vibration of these levers. As the leversswing the shoes rise and fall, but are always kept level, and they givethe grain a tossing or riddling motion.

The motion and weight of each shoe (acting on opposite ends of levers T)counteract the momentum of the other shoe when the stroke is reversed inthe reciprocating motion.

An adjustable wind-deflector, Y, regulates the amount of blast upon thelower shoe and the short riddle F. The deflector acts in connection withthe top board, I), of the lower shoe, directing more or less wind, as isdesired, above and below said board;

The sides of the two shoes are connected by pieces of canvas, Z, inorder to confine and direct the wind; and the lower shoe is partlycovered by an inclined board, 1), upon which the grain falling thereonis carried along by the blast and the shaking to fall through the shortriddle F.

Havingdescribed theinvention,whatIclaim, and desire to secure by LettersPatent of the United States, is-

The combination, with the shoes S S, and mechanism for vibrating them inopposite directions, the shoe S having screen E and inclined board orbottom E, and the shoe S having inclined board 7), short riddle F, andlong riddle G, the adjustable deflector Y, and the blast-fan, of thecanvas Z, for connecting said 5 shoes together at their sides to closethe openings between them, substantially in the man- ELLIS J. HOYLE.
